Some Variables Affecting Risk
Variable Variable Impact
Soil Type Resistivity impacts both current distribution and effectiveness ofthe cathodic protection (CP) system.
Texture can affect coating damage and premature corrosion. Acidity can attack coating and greatly increase corrosion rate. Although not preferred for above reasons, more stable soils
such as rock may be preferable in areas prone to groundmovement.
WallThickness
Increased value increases resistance to TPD and extends depthof pitting before a release occurs.
Increased value is preferred over casings at road crossings forCP.
Increased D/t ratios increase potential for damage from ground
movement.Weights/Hold-downs
Weights increase potential for crevice corrosion, coatingabrasion, and CP shielding.
Weights and hold-downs reduce risk of ground movementassociated with buoyancy issues and hill-side stability.

Summary - 1
API Standard 1160 Is a Holistic Tool for
Planning, Implementing, Evaluating, and
Modifying an Integrity Management Program
Successful Programs Look Broadly at Reducing
Risks Through Risk Assessment and Analyses
Integrity Management Is Important to a
Companys Bottom Line and Reputation, So
API 1160 Address Operators Needs First
Risk Reduction, Not Regulatory Compliance, Is
the Goal of Integrity Management Programs
Managing Pipeline System Integrity Slide 35
Summary - 2
Data Integration Is Essential, a Mechanism for
Integrating Information Must Be Incorporated
Into the Integrity Management Program
A Robust High-Quality Program Requires More
Than Just Regulatory Compliance
New Parallel Guideline onLiquid Pipeline
Security Program Is Being Developed by API
